Wechsler Intelligence Scale for Children-Revised

Wechsler Intelligence Scale for Children-Revised

The Wechsler Intelligence Scale for Children-Revised (WISC-R), a general test of intelligence, which David Wechsler, the test's author, defined as "the global capacity of the individual to act purposefully, to think rationally, and to deal effectively with his environment." In keeping with this definition of intelligence as an aggregate of mental aptitudes or abilities, the WISC-R has traditionally consisted of 13 subtests divided into two parts, verbal and performance. For PHDCN, the WISC-R included definitions of words only. The official Spanish version of the WISC-R (EIWN-R) was used when appropriate.
